    PROJECT

    Conception of a new compressed air system with the requirement for the highest cleanliness and maximum cost-effectiveness

PROJECT INFOS

How the oldest private brewery (“Altbier” brewery) in Germany is preparing for the future

The challenge
Bolten sought a solution for the complete replacement of the existing oil-free compressed air system, which would combine maximum cost-effectiveness with the highest degree of purity. It was also important to stand out against competitor concepts and ensure a 100% oil-free compressed air supply, which must also prove to be particularly costeffective in the long term.

The BOGE solution
The combination of frequency-controlled screw compressors and BLUEKAT converters presented a completely safe solution. It is also particularly economical (not only in comparison with the dry rotors that it was set to replace) and extremely quiet at the same time. In contrast to activated carbon adsorbers, the carbon content of the converters does not have to be changed every year, which is reflected in the pleasingly low maintenance costs.

The result
A sophisticated solution that entails minimal maintenance, and which – thanks to its integrated protective mechanisms – offers the highest degree of safety against the penetration of oil.

    With a company history spanning more than 750 years, they must be doing something right! As Germany’s oldest private brewery, the company Bolten in Korschenbroich explains its lasting success against powerful competitors thanks to their clear commitment to quality and regional focus. Or in the words of the CEO Michael Hollmann, “due to an almost fanatical love of excellent taste”. So that nothing clouds this passion, the compressed air system was scrutinised by BOGE experts, for not only was it loud but clearly also very energy-intensive and expensive to maintain. It was clear that only oil-free compressed air was acceptable, but which system constellation would realise the greatest savings in the long term? The measurement data gave definite hints, but prior to BOGE a competitor had already carried out measurements and proposed a system with activated carbon adsorbers. The decision to use BOGE BLUEKAT screw compressors ultimately hinged on the fact that its converters also hold back silicone and short-chained hydrocarbons, and the compressed air is virtually pasteurised at 180°C.

     

    The purity law of BOGE BLUEKAT
    As compressed air in breweries – from aeration of the wort to enhancement of the fermentation process and from bottle filling to labelling – supports practically every process, the savings potential is naturally correspondingly high if the efficiency of the system is maximised. However, BOGE BLUEKAT technology is not only particularly economical, it is also convincing thanks to its purity in every respect: Oils and hydrocarbons as well as paint-damaging silicon monomers are removed, and the CO and bacterial count of the compressed air are reduced to a minimum.
